SOLDERING DEVIdE.

. I Application Specification of Letters Tatent. Patented Sept. 21, 1909.-

To all :whom it may concern:

Be 1t known that I, FRANK SPENCER CHAPMAN, a citizen of the United States,

and ajresident of Kenton, in the county of Hardin and State of Ohio, have made certain new and useful Improvements in Soldering Devices,-of which the following is a specification.

My invention relates to improvements in means for soldering metallic parts and is especially applicable to those joints used in electrical constructions which require a good. metallic contact-in order to provide against undue resistance to the electric current in the conductors at their point of union.

An object of my invention is to 'provide a device which does away with the necessity of using a furnace or torch or a soldering lI'OIl. r

Afurther object of my invention is to provide a self soldering union for electrical conductors which may be easily applied and which requires no tools for the completion of a good joint. I Other objects-and advantages will appear n the following specification and will be particularly pointed out' in the appended claims.

My invention is illustrated in the accompanylng drawings, in which Figure 1 is a-view of a union embodying my invention. Fig. -'2 is an enlarged sectional view ofthe .union showing two wires before soldering. Fig. 3 is a similar view showing the completed joint. Fig. 4 is a modified form of union. Fig. 5 isa view of a branch union, and Fig. 6 is a sectional view of a piece'of the soldering material.

In carrying out my inventlon I take a sheet of solder A which may be ordinary lead and tin solder, brazing material, zinc, or any suitable material and cover it with a layer B of a compound having, high calorific power when burned. This layer is preferably a mixture of potassiumchlorate, trate of strontium and. powdered shellac in suitable proportions. .This is made into a paste and applied to the solder. The resulting sheet may berolled into sticks or cut up into strips as desired.

filed October 1c, 1908. serial no. 45 7,97e.REISSUED In using the solder, -the surface of the metal to be soldered is first scraped and a flux applied in the usual manner. A piece of the solder with its inflammable coating is then placed on the joint and the heating compound is lighted with a match. It ignites readily and gives an intense heatwhich melts the solder, thus'causing it to adhere v to the surface to be soldered, and doing away with the need of either furnace or soldering iron.

In-joining the ends of two wires I make use of a union C, This consists of a metal tube c having inwardly projecting lugs or flanges 0 near its central part. The tube is filled with solder A, which is cored out at both ends to permit the entrance of the ends of the wires D and E. Outside of the tube there is a ,coatin of heating material B. In effecting the jolnt the wires are first inserted and then the compound B is ignited. During its combustion the heat is conducted to the solder within, which melts and allows the wires to be pushed together until they meet the stops 0. The solder is squeezed around the ends .of-the wires and comes into intimate contact with 'them.-

After cooling the joint presents the appearance shown in Fig. 3 in which the wires D use one-like that in Fig. 4. This consists of-two inte ral tubes C having an inner lining of sol er and an outer lining of heating material. The wires D and E are inserted into the tubes from their opposite ends and are soldered described.

In Fig. 5 I have shown a union for a branch wire. This consists of a split tube C and an integral tube C disposed at an angle thereto. In use the main wire may be placed in the tube (3 by passing-it through the slit 0 while the end of the branch wire is placed inthe tube (1 The inflammable coatingis-i fted and the linings of solder are melt and flow over the 'wires, thus forming a good conducting joint.-
